lvm2_activation_generator: don't create full context for liblvm2app

Browse Source 
Don't use lvm_init() to create a full command context, which
does a lot of command setup (like connecting to daemons), which
is unnecessary for simply reading a value from lvm.conf.

Passing a NULL context arg to the lvm_config_ function is now
allowed, in which case lvm.conf is read without doing lvm
command setup.
